What You Need to Know for Your Exchange 2007 Migration

If you’re like most Exchange administrators, you’ve been following the development of Exchange Server 2007 since the early beta versions and are eager to migrate to it. However, before you insert the installation DVD, you need to know some facts about Exchange 2007 and make some preparations.

The Facts
Exchange 2007 includes many changes and new features. Here are some changes and features that will affect your migration to this new release:

The product is 64-bit only. You must install Exchange 2007 on 64-bit hardware that's running a 64-bit Windows OS. It’s likely that any server you’ve purchased in the past two years is 64-bit capable. If you’re not sure, you should check with your hardware manufacturer or download a free CPU identification utility named CPU-Z from CPUID. (Note that you can’t run Exchange 2007 on Intel Itanium IA64 processors.) Although a 32-bit build of Exchange 2007 is available, Microsoft doesn't support its use in production environments, except for the installation of the management components on 32-bit Windows XP workstations. . . .
